Pregnant Maid

The elder brother who was the top scorer in high school was played to death by the princess. The princess held the whip and smiled viciously: "If you want to blame, blame your poor fate. I had a good fate and became the only dragon fetus." So, what if she is no longer the "only one"? After my rebirth, I was bound to the pregnancy system and became a maid next to the princess. The emperor has no heir, and I am the only one who can give birth to a dragon son for him. I became the most popular concubine, and the emperor was obedient to me. The princess didn't know yet, but this was just the beginning of her bad luck. I want to see with my own eyes her transformation from the apple of my eye to an abandoned pearl in the mud.
